Ultrasound is used in the formulation of coatings for: emulsification of polymers in aqueous systems dispersing and fine milling of pigments size reduction of nanomaterials in high-performance coatings Coatings fall into two broad categories: water-borne and solvent based resins and coatings.
Each type has its own challenges. Directions calling for VOC reduction and high solvent prices stimulate growth in water-borne resin coating technologies. Ultrasound can help formulators of architectural, industrial, automotive and wood coatings to enhance the coating characteristics, such as color strength, scratch, crack or electrical conductivity.
Some of these coating characteristics are achieved by the inclusion of nano-size materials. Ultrasound does further help in the defoaming and degassing of highly viscous products. As ultrasonic dispersing technology can be used on lab, bench-top and production level, allowing for throughput rates over 10 tons/hour it is being applied in the R&D stage and in the commercial production. Process results can be scaled up easily (linear). The devices convert approx. 70 to 90% of the electrical input power into mechanical activity in the liquid. This leads to substantially lower processing costs.
